GAS-PUIFIER.

Specicaton of Letters Patent.

Application filed February 5, 1904. Serial No. 192,074.

T0 all whom/ it may concern.'

Be it known that we, BERNHARD A. SINN and FREDERICK H. WAGNER, citizens of the United States, residing at Baltimore, State of Maryland, have invented certain new and use-l ful Improvements in Gas-Purifiers, of which the following is a specification.

This invention relates to a combined gas washer, scrubber, and purifier, and is particularly applicable for use in connection with a gas apparatus wherein a gas-engine produces a suction which draws the gas from the generator through the washer, scrubber, and purifier' and any intervening apparatus.

The present invention relates to an improved construction of washer, scrubber, and purifier, all of which are contained in a single inclosing shell and operate successively in order that the incoming gas may be thoroughly broken up, washed, and cleaned as it passes through the washer and scrubber to remove the heavier particles carried in suspension prior to passing through the purifier, where the remaining impurities are deposited.

The invention is illustrated in the accompanying drawings, in which-w Figure l illustrates a vertical longitudinal section through the inclosing shell, in which the washer has position at the bottom, the puriiier atthe top, and the scrubber is interposed between the washer and purifier. Fig. 2 illustrates a fragmentary sectional view of that part of the puriiier where the gases enter, being a central vertical section view of Fig. 1. Fig. 3 illustrates a horizontal sectional view through the purifier on the line 3 3 of Fig. l. Fig. 4 is a sectional plan view of the scrubber on theline 4: 4: of Fig. 1, and Fig. 5 is a similar view immediately above lthe washer and on the line 5 5 of Fig. l.

In the drawings referring particularly to Fig. l, A designates a vertical cylindrical shell of air-tight construction provided at its vlower end with a bottom plate a. Within the lower end of this cylinder a ring-plate is riveted to the shell. This ring-plate is provided -with an upper circular ring-flange B and a circular plateb., The. Spa@ ,bGlOW tberlgplate is the washing-chamber A. Arranged above the washing-chamber A and supported by the upper ring-flange B are a plurality of wooden grids C, which comprise a series of trays, each made up of a plurality of horizontal crossed bars c, spaced apart to form square openings c', through which latter the gases from the washer may ascend. This is the scrubber. It will also be seen by reference to Fig. l that the cross-bars which extend in the same parallel direction are arranged so that the square openings formed by the bars of one tray will be confronted both above and below by cross-bars. By this arrangement of tray-bars with respect to each other it will be seen that a series of tortuous passages are Jformed, as indicated by darts, and the ascending gas must travel through these passages on its way to the top of the shell. A plurality of removable plates or doors A2 are provided in the side of the shell, one above the other, by means of which access may be gained to the interior of the shell in order to place the tray-bars in position.

Above the grids or trays C and projecting on the interior of the shell are water-tubes d, provided with spraying-nozzles CZ', from which water is showered down upon the trays and flows through the tortuous passages and scrubs and washes the broken-up gases as the latter ascend through said passages.

A pipe E opens into the shell at a point above the grids or trays C, and said pipe is connected with a vertical branch pipe E, having a valve e, (shown in broken lines,) and above said valve the branch pipe E opens through the shell and into a pocket or receptacle F, which is riveted on the interior of the shell in the purifying-chamber G. This pocket or receptacle is open only at the top, and the gases entering the pipe E are conveyed through the vertical branch pipe E' and discharged into the trough or receptacle F, from which latter they pass out the top opening and enter the purifying-chamber Gr. A

lpurifying-chamber G is provided with a perforated bottom Gr', the bottom surface of lwhich latter is spaced from the horizontal partition g, ,which separates the purifying-cham-v IOO ber from the scrubber. This spacefor-ms apassage-way g'. At one side and near the bottom the chamber G is provided with an upwardlyprojecting hood G2, which is provided with a bottom opening g2 in communication with the passage-Way g. A discharge-pipe G2, having a valve g2, establishes communication between thesaid interior hood G2 and the union connection F. By this system of pipes and valves it will be seen that the gases may be conveyed from the scrubber directly to the union F through the pipe E (the valve e being closed) and branch pipe E2, thereby shunting the purifying-chamber G, or, on the other hand, the gases may be conveyed through pipe E, the valve e being open, and the pipe E into the pocket F and from the latter through the purifier-chamber G, perforated bottom G, passage-way g', hood G2, and dischargepipe G3 to the said union F. This arrangement of pipe connections is provided in order that the gas may be cut off from the purifier to permit the latter to be cleaned or repaired without entirely discontinuing the use'of the apparatus.

The shell is provided in its side near the top with doors h, which permit access to the purifying-chamber G and which when shut lrender the chamber gas-tight.

A cap-plate I fits over the top of the shell and closes the chamber G. This cap-plate is provided with holes t', which are closed lby plates z". A test-cock j is fitted into the capplate I and is in communication with the purifying-chamber G. By means of this cock gas may be permitted to escape through the tube j for the purpose of testing vthe same before it is conveyed to the engine. A drainpipe 7c opens through the horizontal partition g and makes communication with the passageway g and leads down and laterally through the shell A. This pipe is provided with a valve, (not shown,) which may be opened when the valves e and g3 are closed in order to permit' of draining the chamber G when the doors /t or holes z' are opened.

A gas-inlet pipe n leads from the gas-generator (not shown) and has a valve m and is tapped into the washing-chamber Al and supplies the crude gas into the shell at its bottorn.

A pipe L, attached to the union F', leads to the engine. (Not shown.)

A liquid-seal trap O of any suitable construction is provided at the bottom of the shell and in communication with the washing-chamber A. By means of this trap the water from the scrubber passed -into the washer A is permitted to pass off without allowing the escape of the gases. The water seal will maintain the water in the washing chamber at height suflicient to keep the bottom flange b3 submerged.

In the operation of the device the incoming gases by Way of pipe n are discharged into the washing-chamber A', where by the operation of the annular bottom liange 52 they pass down in the water and then up yto the circular plate b. Here the gas contacts with the knobs or teats b2 and finds egress through the rperforations ZJ. While ascending through said perforations, the gases are met by the descending water. The gases then pass up through the tortuous passages of the scrubber, where they are thoroughly broken up and washed and pass out through the pipe E and then enter into the purifying-chamber G, as heretofore described. Thischamber G is preferably filled with wood shavings, where the remaining impur-ities are deposited. If the gases contain any tar, this treatment is most effectivefor removing the same. The gases pass down through the shavings and through Vthe perforated bottom G' into the passage-way g. From the passage-way g the gases pass up through the hood G2 and are conveyed by pipe G3 to the union connection F and from the latter are discharged into a pipe L, leading toward the engine or to a 7dust-arrester, as desired.

vHaving thus fully described our invention, what we claim as new` and desire to secure by Letters Patent, isv 1. In an apparatus of the class described the combination with a shell, of a ring-plate within the shell and at the lower end thereof, said ring-plate having acentral perforated depression and an annular bottom flange which projects below said depressed center; a waterchamber in the bottom of said shell beneath said ring-plate; a gas-inlet pipe entering the shell below said ring-plate and at the side of said bottom flange; a liquid-seal trap also at the bottom of said shell and below said ringplate; a plurality of grids above said ringplate; a partition in the shell above the grids vto form a-chamber; a receptacle in said chamber; a pipe having one end opening into the shell above the grids and the other end `opening in said receptacle in the chamber above the grids, -and a gas-discharge pipeconnected to the shell above the said partition. 1
